SAFETY SUMMARY
Please read these instructions carefully before using your LP 740.
Failure to comply with them could result in fire, electrical shock,
personal injury or damage to equipment.
These graphics are used throughout this manual to draw your
attention to important information about the projectors.
NOTE: Additional useful details or tips.
CAUTION: Steps to take to avoid damage to your equipment.
WARNING: Steps to take to avoid personal injury.
These graphics are used on the projector’s labels.
Attention - Refer to this User’s Guide for important
safety information.
CAUTION-Hot Surfaces - Avoid touching hot surfaces.

Do Not Look Into The Lens!
Be extremely careful not to look into the projection lens when the projector is turned on. The bright light may harm your eyes. Be especially careful to keep children from looking into the lens.
Power Source
Use only a three-wire grounding type power source. The power source
should not exceed 250 volts rms between the supply conductors or
between either conductor and the ground.
Power Cord
Use only the power cord that was shipped with the projector. Although
other power cords might be similar in appearance, they have not been
safety-tested with the projector. Do not use a power cord if it has become
damaged or frayed. Contact your In Focus dealer or call In Focus if you
need to replace your power cord.

Grounding
The projector is grounded through the grounding conductor on the
power cord. To avoid electric shock, plug the power cord into a properly
wired receptacle. Do not defeat the purpose of the grounding-type plug.
Lamp
To avoid overheating and unacceptable image quality, replace the projection lamp with a lamp of the specified type. Refer to page 33 for lamp
specifications and to page 26 for instructions on replacing the lamp.
Lamp Compartment
To avoid burns, do not open the lamp module door until the projector is
turned off and the lamp has cooled for at least 30 minutes. Follow the
instructions in this manual for lamp replacement carefully.
Hot Surfaces
Allow the projector to cool at least 30 minutes before replacing a lamp.
When you open the lamp housing, be very careful not to touch the hot
surfaces inside.
Ventilation and Overheating
Openings in the projector case provide ventilation to protect it from
overheating. Keep loose papers and other objects well away from the
grills. Do not place the projector on top of or close to a computer or other
heat-producing equipment.
Liquid Spills
Do not set drinks on top of the projector. Spilled liquids can flow inside
and cause damage.
NOTE: If you open the projector
case, you will void the warranty.
iv
Do Not Disassemble
All service must be performed by an authorized In Focus service center.
The only user-serviceable part in the projector is the projection lamp,
which you can replace by opening the lamp cover on the bottom of the
projector (see page 26). Do not open any other part of the projector. If
your projector needs repair, call your local Authorized Service Provider
or In Focus Technical Support as described on page 4. Before you call,
refer to “Troubleshooting” starting on page 29 to see if you can resolve
the problem yourself.

Usage Guidelines
• Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.
• Do not block the grills on the projector. Restricting the air flow
can cause it to overheat and turn off. If this happens, you must
wait a minute before attempting to turn it back on.
• Handle the projector as you would any product with glass
components. Be especially careful not to drop it.
• Avoid leaving the projector in direct sunlight or extreme cold
for extended periods of time. If this happens, allow it to reach
room temperature before use.
• This projector is not intended for use in a mainframe computer
room as defined in the Standard for the Protection of Electronic
Computer/Data Processing Equipment, ANSI/NFPA 75.
• Transport the projector in a vendor-approved hard or soft case.

MAINTENANCE & TROUBLESHOOTING
This section describes how to:
•clean the lens
•clean the fan filter
•replace the projection lamp
•troubleshoot the projector
Cleaning the Lens
Follow these steps to clean the projection lens:
1 Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
• Avoid using an excessive amount of cleaner.
• Abrasive cleaners, solvents or other harsh chemicals might
scratch the lens.
2 Lightly wipe the cleaning cloth over the lens.
3 If you don’t intend to use the projector immediately, replace
the lens cap.
Cleaning the Fan Intake Filter
The fan intake filter on the bottom of the projector catches dust
and particles in the air. If the filter becomes clogged, the projector
does not cool properly and may malfunction. To prevent this,
clean the filter after every 100 hours of use.
1 Turn off the power and unplug the power cord.
2 Remove the filter door (Figure 15).
• Remove the screw on the filter door and lift the door out.

3 Clean the filter.
• Use a vacuum cleaner set on low power to remove the dust
and dirt.
4 Re-install the filter.
Replacing the Projection Lamp
WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you open
the lamp module door. Never
extract the lamp module while the
lamp is operating.
The lamp hour counter in the menus counts the number of hours
the lamp has been in use. The LP 740 uses a metal halide bulb.
These types of bulbs deteriorate over time. Replace the lamp
when the brightness is no longer acceptable. The lamp LED
blinks slowly after 950 hours; it blinks more rapidly after 1000
hours. You can order new lamp modules from your In Focus
dealer. See “Accessories” on page 34 for information.
Follow these steps to replace the projection lamp:
1 Turn off the projector and unplug the power cord.
2 Wait 30 minutes to allow it to cool thoroughly.
3 Place the projector on its side, then remove the 2 screws on the
lamp module door (Figure 16).
4 Pull the lamp door up and remove it.

WARNING: Do not drop the
lamp module or touch the glass
bulb! The glass may shatter and
cause injury.
8 Gently push the module in as far as it goes.
9 Tighten the screws on the outside of the module.
10 Re-install the lamp door.
11 Plug in the power cord and turn the projector back on.
12 To reset the lamp hour timer in the menus, press and hold the
Track and Sync buttons, then press the Power button (while
still holding down the other buttons) for 3 seconds. Verify that
the timer was reset by pressing the menu button, navigating
to the Information menu, and viewing the Lamp Timer setting
(see page 22).

Troubleshooting
Problem: Nothing on projection screen
•Make sure that the power cord is properly connected to a functional AC electrical outlet. Make sure that the power cord is
also properly connected to the projector.
•If the projector is plugged into a power strip, make sure the
power strip is turned on.
•Make sure you have removed the lens cap on the projection
lens at the front of the projector.
•Make sure the projector is switched on.
•Check the projector’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection
Lamp” on page 26.
•Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
•You might need to adjust the brightness up or down until the
text is visible. Refer to “Bright” on page 15 for more information.
Problem: The screen resolution is not right
•Make sure the computer’s video card is set for a resolution of
no greater than 1280x1024.
Problem: Image isn’t centered on the screen
•Reposition the image. Refer to “H-Position, V-Position” on
page 18.
•Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the blue start-up screen displays
•Verify that the cables are connected correctly. See page 7
through page 8 for connection procedures.
•Verify that the proper input source is connected. See “Source”
on page 14.

•You might need to turn everything off and power up the
equipment again in the proper order. Refer to your computer’s documentation to determine the correct order.
•Make sure your laptop’s external video port is turned on. See
the “Portable and Laptop Activation Chart” on page 35 or
your computer’s manual for details.
•Make sure your computer’s video board is installed and con-
figured correctly.
If you’re using Windows 3.x:
1 In the Windows Program Manager, double-click the Windows Setup icon in the Main program group.
2 Verify that the Display setting is 1280x1024 or less.
If you’re using Windows 95:
1 Open “My Computer” icon, the Control Panel folder and
then the Display icon.
2 Click the Settings tab.
3 Verify that the Desktop area is set to 1280x1024 or less.
Also check the following:
•Does your computer have a compatible video board? The pro-
jector isn’t CGA or EGA compatible.
•Is your computer’s video port activated? This is especially
true for laptop computers. See “Portable and Laptop Activation Chart” on page 35.
Problem: Image is too wide or narrow for screen
•You might need to manually adjust the tracking to reduce or
enlarge the projected image. Refer to Tracking on page 18.
•Adjust the resolution of your video card if it’s greater than
1280x1024 pixels.
30
Problem: Image is out of focus
•Turn the projection lens to focus the image.
•Make sure the projection screen is at least 5 feet (1.5 m) from
the projector.
•Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
•Rear projection mode is probably turned on. Turn “Rear” off in
the Custom Setup menu. The image should immediately
return to forward projection. See “Image Mode” on page 21.
Problem: the projector displays vertical lines, “bleeding” or
spots
•Adjust the brightness. Refer to “Bright” on page 15 for more
information.
•Check the projection lens to see if it needs cleaning.
Problem: no sound
•Adjust volume.
•Verify audio/input connections.
•Adjust audio source.
Problem: Image is “noisy” or streaked
•Adjust the synchronization and tracking manually to find an
optimal setting. See Sync and Tracking on page 18.
•The problem could be with your computer’s video card. If
possible, connect a different computer.
Problem: Projected colors don’t match the computer or video
player’s colors
•Adjust the brightness, tint and/or contrast from the menus.
Just as there are differences in the displays of different monitors, there are often differences between the computer image
and the projected image. Refer to “Bright” on page 15, or Tint
or Contrast on page 18.

Using Video Mirroring with a PowerBook Computer
When you turn video mirroring (called SimulScan in newer PowerBooks-see below) on, the projector displays the same information that appears on your PowerBook’s built-in screen. When
video mirroring is off, the projector acts like a separate display.
To turn on video mirroring for the first time:
1 Open the Monitors control panel; click on Monitor 2.
2 Set the number of colors you want.
3 Open the Control Strip; click on the monitor icon.
4 Select “Turn Video Mirroring On.”
Now you can turn video mirroring on and off from the Control
Strip without having to open the Monitors control panel again.
When using video mirroring and high color graphics such as
slide shows, the projected image occasionally might turn black
and white. If this happens, perform the following steps:
1 Turn off video mirroring.
2 Open the Monitors control panel.
3 Move the white menu bar to Monitor 2 to set the projector as
the primary monitor.
4 Restart the PowerBook.
Using SimulScan
Some newer PowerBooks display images on an external monitor
or projector differently than previous ones. When using
SimulScan, the projector displays the same information that
appears on your PowerBook
To select SimulScan:
1 Open the Control Panel, then double-click Monitors and
Sound.
2 In the Resolution list, choose the SimulScan mode, then click
OK.
3 If this changes your display settings, a dialog box appears.
Click OK to confirm the change.
